Lab question: cleaning glass


How can glass (beakers, flasks, etc.) be cleansed of acrylic polymers(*) which are insoluble in water without using a lot of organic solvents? I am searching for an environmentally friendly way of cleaning lab equipment.

TIA, Oliver

(*) highly viscous, strongly adherend, glue-type polymer

I would try methanolic KOH. Frank

You are a bit late... ;-)

It is not possible to fill the flask completely with acetone and then you have still spots with some tacky residue (or acetone-spills dry: same problem).

I have tried most of the suggestion and I will stick to the methanol(ispropanol/ethanol)/KOH solution.
